Preparation of mesoporous silica using amphoteric surfactant potassium and sodium N-dodecyl glycine template

Mesoporous silica with hexagonal structure and Pm (3) over barn cubic structure with an ordered and parallel arranged pore channel has been synthesized using potassium N-dodecyl glycine and sodium N-dodecyl glycine as template, respectively. Their ordered mesostructures were characterized by infrared spectroscopy, small X-ray diffraction patterns, SEM, transmission electron muicroscopy, and nitrogen sorption analysis.
